The Palm people responded to my email very quickly, telling
me that the barebones version of the palm pre FOSS site is
up, and will be populated with source and packages in
about 2 weeks.

I haven't heard anything yet on how locked down the phone
will be. The initial version of the phone is CDMA,
but a GSM version is under development.
Hopefully people will be able to reimage the device to load
a new OS and will not be thwarted by some kind of tivoization.
